Flanderization is what I've also loosely called "caricaturization" actually. Think of how Kevin in the office started out but then look at how he changed because of the cookie monster bit. It was a definite, noticeable shift in his character.

I agree with the rest too. I can concede to the Lisa analysis. I'm really recalling watching the show back when I identified as a Dem so was probably conflating what I thought "the left" was at that time.
